Embodiment 1

[0034] Such as figure 1 As shown, the UAV induction motor comprehensive test bench includes the experimental bench 1, the upper computer 2 and the motor test group; each motor test group has a motor mount 3 for installing the motor to be tested. The motor to be tested is connected with a speed sensor and a torque sensor. It also includes a tension sensor 4 and a slide rail 5. The motor mount 3 is connected to the upper end surface of the test bench 1 through the slide rail 5. One end of the motor mount 3 is connected to a separate metal rope 6, and each metal rope 6 is connected to a separate tension sensor 4. One end is connected, the other end of the tension sensor 4 is fixed on the test bench 1 , and the tension sensor 4 is electrically connected with the host computer 2 . It also includes a UAV propeller, which is connected with a torque sensor through a coupling.

Embodiment 2

[0043] In this embodiment, a drone with 4 propellers is only installed on the upper end of the drone body. The user first inputs n=4 on the host computer 2, and the current air density is 1.185kg / m 3 , according to the angle of attack of the propeller, the pull coefficient obtained from the table is 0.6, and the area of ​​the propeller is 40cm 2 , the length of the blade is 12cm, the mass of the drone is 240g, and the flight mode is hovering. The host computer can calculate the theoretical rotational angular velocity of each propeller. Theoretically, the lifting force generated by the four propellers at this time is the weight of the drone. According to this value, the speed of the propellers can be obtained as 120r / min.

[0044] When testing the motor, the microcontroller controls the motor to run, and detects the speed, torque and voltage and current of each motor. The upper computer calculates the input power, output power and efficiency of the motor. Then attach the pr...

Embodiment 3

[0046] In this embodiment, a drone with 8 propellers is tested only on the upper end of the drone body. The user first inputs n=8 on the host computer 2, and the current air density is 1.185kg / m 3 , according to the angle of attack of the propeller, the pull coefficient obtained from the table is 0.6, and the area of ​​the propeller is 40cm 2 , the length of the blade is 12cm, the mass of the drone is 240g, and the flight mode is hovering. The host computer can calculate the theoretical rotational angular velocity of each propeller. Theoretically, the lifting force generated by the 8 propellers at this time is the weight of the drone. According to this value, the speed of the propellers can be obtained as 85r / min.

Abstract

The invention relates to the technical field of motor testing, and discloses an integrated test stand for an unmanned aerial vehicle induction motor and a test method. The integrated test stand for the unmanned aerial vehicle induction motor comprises an experiment platform, voltage and current detection modules, torque sensors, speed sensors, a microcontroller, motor driving modules, tension sensors and an upper computer, and is characterized in that the microcontroller is controlled to output PWM signals to each motor driving module; the sensors and the measurement modules detect physical variables and transmit detected values to the upper computer; and the upper computer calculates according to the data and displays a result in the form of a diagram. In order to reduce the interferenceimposed on the measurement process of the tension sensors, the integrated test stand adopts a sliding rail design to reduce the pulling friction. According to the invention, an external circuit and internal control signals of the unmanned aerial vehicle motor are simulated, the experiment can be conducted by being close to characteristics of the unmanned aerial vehicle motor, the application rangeof the experiment data is wide, the accuracy is high, and the upper computer autonomously completes the calculation process, thereby being more time-saving, and being more reliable in experiment result.

Description

technical field [0001] The invention relates to the technical field of motor testing, in particular to the design of a comprehensive testing platform and testing method for an induction motor of an unmanned aerial vehicle. Background technique [0002] In recent years, with the development of microelectronics, navigation, control and communication, it has also promoted the development of the drone industry. UAVs are extremely versatile, not only bringing convenience to ordinary people in civilian use, but also appearing in military UAVs in the future military construction. Therefore, it is very important to design a test bench for testing UAV motors It has practical value. Most of the existing motor testing technologies are aimed at common motors in the market. Although they can be used to test UAV motors, there is no way to test the output characteristics of UAV motors after they are connected to propellers in the prior art. has limitations. In addition, during the test ...
